Tradeoff analysis of high-power electric propulsion systems based on domestic electric propulsion engines and potential for their use in orbit-to-orbit transfer systems and deep space exploration

The paper discusses design solutions for increased-power and high-power electric rocket propulsion systems to be used in orbit-to-orbit transfer vehicles and advanced spacecraft. It reviews characteristics of their components from the standpoint of the mission to reboost the spacecraft to their target orbits, to perform the operations of transportation to the lunar orbit and to explore deep space. It discusses key criteria and procedures for selection of components, as well as problem areas in their development and ground developmental testing. The paper analyses pros and cons of using various versions of propulsion systems based on medium- and high-power electrical propulsion engines, the current status of their component development, as well as the technical feasibility of conducting developmental tests on the ground.
